Drivers are concerned with the mileage obtained by their automobiles. One driver has kept track of several tankfuls of gasoline by recording miles driven and gallons used for each tankful. Develop a C++ program that uses a while statement to input the miles driven and gal- lons used for each tankful. The program should calculate and display the miles per gallon obtained for each tankful and
print the combined miles per gallon obtained for all tankfuls up to this point.c Enter miles driven (-1 to quit): 287 Enter gallons used: 13 MPG this tankful: 22.076923 Total MPG: 22.076923 Enter miles driven (-1 to quit): 200 Enter gallons used: 10 MPG this tankful: 20.000000 Total MPG: 21.173913 Enter the miles driven (-1 to quit): 120 Enter gallons used: 5 MPG this tankful: 24.000000 Total MPG: 21.678571 Enter the miles used (-1 to quit): -1
